. This invention has reference to means that have been devised for use in the formation and surfacing-lot roads and lilze'fonnations,

l streams spread over the L width andespecially "to means that are adapted to the formation of tar and 'bittunen sealed roads and'inwhich' sand, gravel and like discrete materials are required to be spread in an even manner over surfaces" coveredv by the liquid tar or bitumenwhileitstill hot so as to beincorporated therewith. f The The invention consists broadly in the-cont bination with a lorry, Waggoner like vehicle delivered into these passages. .or channels and; by them, divided int'o "a nungiber, .ot

the spreader and which streams gravitate down ina fanyvise'rnanner.

There may be con bined with the spreader, a gr d that 1s disposed over its top, and

"which serves to screen off. .1 ;ny 1ngettq1'der such as would block theisaid'channels, for

The invention is illustrated inthe accompanying drawings as applied to a lorryhaving two discharge openings, but it of construction may be applied to lorry having a single discharge jo tiening or inior'e than two openlngs.
